Ok mate, I'm gonna give you some help.
First up, indeed you will need a program like Gimp or Photoshop to do sphax texturing. MS Paint just won't cut it. It is very disappointing that you can't get cs2 working, and I'm very confused why you can't.
Although if you do get around to getting a good photoshopping program with VECTORIAL tools then you may need a tutorial or two to learn the basics and rules of sphax texturing.
This link goes to the forum thread where sphax tells you the rules and examples of how shadows, inner glows and strokes work:

This one is a few PSD downloads for texturers of basic items commonly used in texturing mods:

Now there is more than that if you are looking for some more in depth teaching of how to texture.
There are Sparkster's tutorials:

Then there are mine:

There is much more to fine out there.
As for you textures, I must agree with pesti, they are just not sphax textures.
Here is an example of my version of the magical stick:

I wish you good luck in your texture making!
